Hi @mehranes

Maybe you can follow this guide to found the issues.

Some extra recommendations:

-Review the physical condition of the devices, pay specific attention to the antenna and connector.

-If it’s located in a building maybe you can move near to windows or test in other locations only to discard that it’s a problem related to the building.

-If you are using the manual mode, first try to use the automatic mode to be sure that all the hardware is well.
